At this point let’s post-heat our air, bringing it back to +20°C . The air has kept the same absolute humitidy (4,384 g of water vapor), but its relative humidity is now 30.18%.
The following diagram represents the entire cycle:
From point A to point B with no dehumidification .
From point B to point C cooling and dehumidification .
From point C to point D post-heating .
